TALLADEGA, AL (WIAT) – A national championship winning quarterback and an 8-time Major League Baseball All-Star were on hand at NASCAR’s fastest track Sunday. Alabama’s AJ McCarron is used to being behind the power of the Tide offensive line, but he took the lead in-front of the pack of 43 stock cars by driving the pace car. He was joined by former Atlanta Braves star Chipper Jones, who served as the Grand Marshal of the Aaron’s 499.
